Hi, This is a new problem, actually the first I've had with it since I installed it when first released. Starting just today I can't use my PMDG 737 without it crashing Flight Simulator. The only change I've made to Flightsim since I last flew the 737 was installing and uninstalling the SGA MD83 and Panel. Do I need to reinstall the 737? Any ideas of what could be causing this? Thanks,William

Okay, I'll answer it myself. :-) I did a complete uninstall and reinstall. That seems to have fixed the problem. Whatever the problem was.....William

Yep, I agree with William; Reinstall!Be patient about the update! :-)/Bj
